Description

Technical Field

[0002] A digital height gauge is an instrument used to accurately measure the height of a workpiece or determine a specific point on a plane. It usually consists of a vertical stand and a moving measuring head, on which sensors and a digital display are installed to display the measurement results. The working principle of the digital height gauge is based on the sensor measuring the distance from the top of the workpiece or a specific point to the reference surface. After the measuring head moves to the target position, the sensor measures the distance and transmits the data to the digital display, which shows the corresponding height value. Users can easily read and record these digital values ​​for further analysis or processing. In practice, error detection is usually carried out by comparison with a known standard or by using a calibration object for inspection. This helps to detect and correct any possible measurement deviations in a timely manner, ensuring that the performance of the height gauge is in the best condition.
